Marketing of Mushrooms
Mushrooms are marketed as fresh, frozen, canned, marinated, freeze-dried and tunnel
dried mushrooms.
Freeze-Dried Mushrooms
Freezing the mushrooms, then placing them in a vacuum where they remain frozen until
all water is removed. That process is called freeze-drying and is very expensive, both for
energy and for the required equipment.
Tunnel-Dried Mushrooms
A tunnel drier consists of a blower to circulate air, a heater to increase the temperature
of the air to approximately 40 to 50°C (104 to 122°F), and a chamber to put the food to be dried. Tunnel drying will give a high quality product.
